Claims
- 1. A display device driving method in which image data, which expresses respective densities of dots by first dot data of a predetermined bit length, is converted into a plurality of frame data, which expresses respective densities of dots by second dot data which is shorter than said predetermined bit length, so as to drive a display device by said plurality of frame data, said display device driving method characterized by converting image data into a plurality of frame data by making data, from which a least significant bit of said first dot data has been removed, into said respective second dot data of said plurality of frame data, and in a case in which the least significant bit of said first dot data is 1 and a most significant bit is 0, adding 1 to a corresponding portion of said plurality of second dot data, and in a case in which the least significant bit of said first dot data is 0 and the most significant bit is 1, subtracting 1 from a corresponding portion of said plurality of second dot data, said plurality of frame data representing at least three successive frames of data.
- 2. A display device driving method according to claim 1, wherein in a case in which a difference between one of said first dot data and another one of said first dot data whose most significant bit is 1 and the other bits are 0 is small, a number of second dot data for which said addition or said subtraction is effected is decreased, and in a case in which said difference is large, the number of second dot data for which said addition or said subtraction is effected is increased.
- 3. A display device driving method according to claim 1, wherein a liquid-crystal display at which a thin-film transistor is provided in correspondence with respective dots is used as said display device.
- 4. A display device driving method according to claim 3, wherein image data is converted into three frame data.
